Its commonly used for HD video playback, which nonetheless leads to large space-hogging file. It has the least compatibility unless you install MKV codec pack. But if you stress on quality, MKV is preferred.

• Rip DVD to MP4 Pros: MP4 has smaller file size than AVI and MKV, with a good balance between size and quality thanks to its high compression rate. It allows for sending a copy of movie, streaming over the internet and uploading to web, making it accessible to wide users of iPhone, iPad and other mobile devices.

Common Problems and Errors in DVD to MP4 Ripping

Mac has no built-in DVD ripper, though there are add-ons for DVD playing and burning, such as Mac DVD player and iDVD. This is because DMCA claims the illegality of circumventing any copy protections that are generally put on all commercial discs. But you can still find pieces of free DVD converter software available to get movies off discs and turn into MP4, such as Handbrake, VLC, Mac The Ripper, etc, which are well known as free open sources but also poses on many problems in DVD ripping.

1. Unable to Rip Commerical DVD Movies due to the Protection Measures
DVD protection is used to restrict usage of copyrighted works such as commercial DVDs. Nowadays, almost all commercial DVDs are encoded with complicated protection schemes that weed out common DVD converters and manifest in various errors, such as 'DVD ripping unexpectedly crash', 'takes forever to rip DVD movies', 'sector read error', etc. Even with the renown libdvdcss installed on Mac, some software such as Handbrake is reported to only rip regional and CSS-protected DVDs and inform you of no valid source found error, or rip only the first 30 seconds of the movie to MP4 and then it stucks in the rest 2-hour movie ripping process, when facing with typical discs, from, e.g. Disney.

2. Slow DVD to MP4 ripping speed
When it comes to speed, there are two factors need to be considered: DVD ripper and the computer itself. Higher computer configuration will lead to better DVD to MP4 decoding and encoding performance. But good ripper will take full use of CPU core and GPU encoding to greatly accelerate the DVD to MP4 ripping speed. This seems indispensible especially when you have a large DVD collection. According to the forums, many users report it takes more than 30 min to rip a full-length DVD movie to MP4 using DVDRemaster, even on a highly configured Macbook in hand.

3. Get blurry/pixilated image After Ripping
We rip DVD not only for backup but also for pleasant playback. So the ability to output high-quality MP4 file is deemed as essential in choosing a DVD ripper. But the truth is most free DVD to MP4 ripper for Mac or PC is not satisfactory. For example, posts on reddit indicate that some tools gets fuzzy and pixilated results that are definitely unwatchable, even though they higher the bit rate. Some users shares their complains on forum.dvdfab that they get the horizontal interlacing lines in the ripped video and the de-interlacing option is greyed out. That's not the end. It results in no sound though the picture is great.

4. New DVD Movies won't Rip
New released DVDs are not supported by almost all the DVD rippers on the market, especially freebies. For example, the new movies that users reporting most errors including Venom, Incredibles 2, Deadpool 2, Jurassic World: Fallen Kingdom, Hotel Transylvania 3, Mission: Impossible and some more. Errors they met including:
* The program can't find the correct title of the movie.
* The audio drops out occasionally and won't come back with the Atmos track.
* Error message indicates that the source file is corrput or invalid.
* Failure to open the disc.
* DVD ripping stops at x% ...

5. The Picture Size of MP4 is All Wrong
It's known to us that the resolution of PAL DVD is 720x576 and NTSC DVD goes to 720x480. Generally, the output MP4 file is kept with DVD original settings if nothing has changed on the parameter settings. However, some users find that they get their ripped MP4 file with wrong picture size, automatically vertically stretched, which mismatches with their playback device iPhone 6s Plus. They wonder if they can crop image size to solve this issue before DVD conversion.

6. Difficult to use
It makes a lot of sense to download an easy-to-use program. For example, you might be a green hand, unknown about any parameter settings for either high quality or small file size. You are lazy to go any further steps to fit your mobile devices. Some software such as iSkysoft DVD ripper touts many add-ons that confuse you a lot but doesn't manage to output high quality image.

Please note that the latest macOS 10.15 Catalina is killing off 32-bit apps, including QuickTime 7. So make sure your DVD ripper is upgraded with 64-bit version and has good compatibility with the Catalina.

Guide to Decode a DVD to MP4 on macOS Catalina or Earlier

First of all, get the software: Free download the DVD converter on Mac

Step 1. Load DVD Movies or DVD Folder.
Run the converter and click 'Disc' button to import the DVD files. You can also choose to rip DVD Video_TS folder to MP4 or convert ISO to MP4 by clicking 'Path' button. After a few seconds, all DVD titles will be listed and the main title will be automatically selected.

Step 2: Choose MP4 as Output Video Format.
Here we choose MP4 Video encoded with H264 + AAC from General Profiles category as output format. There is a slide bar available for you to adjust quality and speed. Generally faster speed comes at the price of worse quality and vice versa.

Note: You can tweak the parameter settings such as upping the bit rate, resolution, etc to get the best output quality or lowering these settings to ensure a fast DVD to MP4 converting speed. But you have to know that high quality usually leads to slow ripping speed and huge size. This tool helps to reach the perfect balance between quality, speed and size, even you only leave its default profile unchanged.

Step 3: Opt for Desired Subtitle Track.
Tap the expand icon at the selected main title to open the multiple subtitle tracks list where you can select your desired one, e.g., English, French, Spanish, Forced subtitles only, disabled subtitle or load subtitle you downloaded or made by your own.

The same applies to choose audio track that is next to subtitle option. Basically, DVD provides you with AC3 audio with 6 channels. If you just playback DVD digital movie on iPhone iPad Android, audio with 2 channels is actually enough and it can save much space for you.

Shift your attention to the lower right corner of the main interface, where you're suggested to manually tick 'High Quality Engine' and 'De-interlacing' options in case output quality is your top priority.

Step 4: Select Output Folder.
Click 'Browse' to choose the path for output files storage.

Step 5: Start Conversion.
Now tap 'RUN' button to start conversion. The pop-up DVD conversion window will show you the processing percentage and the GPU hardware acceleration tech it utilizes: Intel QSV, Nvidia or AMD if your hardware configuration is qualified. GPU HW acceleration tech hands over the DVD ripping tasks from CPU to GPU so as to relieve your CPU from computing-intensive tasks, solve CPU overusage/overheating problems and speed up DVD ripping 5X faster than any competitor.

MacX initially features GPU accelerated HEVC encoding. This is especially helpful for Apple users working with the latest macOS Catalina or iOS 13. By converting DVD to HEVC MP4, you will shrink a 7.84GB DVD into a file that is less than 1 GB and therefore store more movie contents on your Macbook, iMac and enjoy them on your newer iPhone or iPad with higher image quality.

Verdict: if you have a lot of new movies on DVD and want to make a backup, the 'copy' feature lets you copy main title to MPEG2, backup full title with all videos/audios/subtitles, and make 1:1 copy of DVD to ISO image with original video/audio in few minutes on Mac.

Recommendation 2: How to Free Convert DVD to MP4 format on Mac with Handbrake V1.1.1

Handbrake is a popular program that can deal with DVD to MKV/MP4 conversion on Mac freely. But you have to notice that Handbrake, even the latest version V1.1.1, rips protected DVDs with the help of VLC libdvdcss. Sometimes it ends up with no valid source found or only first chapter/30 seconds rip when it comes to decrypting newly released DVDs. You might also need to know that the good reputation of Handbrake is spotted by its poor compression ability and high CPU usage (almost 90%), to certain degree.

Of course, a DVD ripper without any flaw could never be found. As for the unprotected DVD discs, the outcome is satisfactory. So if you have unprotected DVDs and want a disc to MP4 processing, Handbrake still deserves your trial. Below is the step by step guide on how to convert DVD into digital MP4 on macOS with Handbrake.

Step 1: Free download and run Handbrake V1.1.1 on Mac.
Step 2: Select a source DVD (no DRM) you need to rip to MP4.
Step 3: Choose a title. Generally, the title with the longest duration is thought as the right title. If No valid source found pops out, it may indicate that the DVD is encrypted. For this part, please turn to VLC to read the DVD and find the right title.
Step 4: Choose the output format MP4. You can also go to Toggle presets to select the device profiles at the right window.
Step 5: Do some setting adjusting. You can adjust the video setting, audio setting, subtitles, and more if you are skillful at this Mac application.
Step 6: Click Start button to begin the ripping process. Due to the lack of GPU hardware acceleration tech, it mainly relies on your CPU and might consume your CPU up to 90% so that you'd better shut down other tasks.

For Mac manufactured before 2017, just choose MP4 H.264 for smooth DVD ripping. If you have newer models, you can feel free to rip DVD to MP4 HEVC, since the newer models have more powerful CPU and GPU to encode HEVC. Also make sure to have the GPU accelerated DVD ripper to do the MP4 HEVC encoding.
