Fix for MKV MP4 720p 1080p Stutter Freezing issues
If you already have a large movie/anime collection, chances are that you have video files in either MP4 or MKV format.
While these formats are quite common, unfortunately playback support for these files is quite limited.
MKV is only supported by video players such as HD MKV Player, HD Player, 8player and AV Player HD, and while the MP4 is supported by the iPad's video decoding chip, the settings used to create these video files are often not optimized for iPad playback.
Players such as HD MKV Player, HD Player, 8player and AV Player HD overcome this by using a technique called software-decoding, which uses the iPads processor to decode the video file. Aside from a higher power consumption (the battery drains quicker), and the hassle to put these files on your iPad, depending on the performance of your iPad (iPad 2 is less powerful than the iPad4), as well as the format (H264, DIVX, XVID, VC1) and resolution (720p/1080p) of your MP4 and MKV files, chances are that you run into playback issues such as stuttering video, freezing video and lip movement not matching up with the actual voices.
Some players work better with some files than others, so you could install multiple players and when you run into issues with one, you try the video in another player, but, aside from the hassle of copying the videos over again, this causes an interruption with your movie watching experience.
The best solution to overcome these issues is to convert your videos to a format that is supported by the video decoder chip, aka hardware decoding.
A quick google search will bring up a large collection of different conversion tools that can help you with this, but unfortunately, the majority of these require you to either convert files one at a time, or only offer a batch-conversion mode that uses one quality option for whatever you convert.
If you have a large collection of different types of videos, SD resolution such as DVD-sized or HD content in 720p or 1080p resolution, using 1 fixed setting for all your conversions results in larger-than-needed file-sizes (a 2-hour DVD-sized movie will end up just as large as a 2 hour Bluray sized movie).
The best option to use for this is DVD Catalyst 4.
Originally developed to make the conversion of a large amount of video files a lot easier, it enables you to simply drag & drop your files, folders, or even drives filled with your video files, on top of the program,
and it will convert them all in batch mode with a single click.
one video file, a TV show season, or even a full Anime series, just drag and drop and tap Go.
The best thing about DVD Catalyst 4, aside from having profiles for just about any device capable of video playback (Android devices such as the Motorola Xoom, Kindle Fire HD, Galaxy S3, Nabi 2, Nexus 7, Apple iPad 1-4, iPad Mini, iPhone and iPod, and even car DVD players and child-tablets like the Innotab 2) is that it has "smart" conversion profiles.
These "smart" profiles use special settings (the HQXT profiles, available for most popular devices) that automatically adjust themselves during the conversion to produce the best quality video, regardless of the (SD/HD) resolution of your original videos, and activity.
Rather than using a fixed “bitrate” (Kbps) quality setting, which is what most conversion tools use, DVD Catalyst's HQXT settings use fixed “visual” quality settings.
For example, using "fixed bitrate" settings, a 2 hour movie converted with 2000Kbps will always end up around 2GB in size. SD, DVD, Bluray, HD 720p, HD 1080p, romanceor the latest action blockbuster, no difference.
But, the visual quality will be quite different. For SD, 2000Kbps will be fine for both romance and action videos, but if you go up in resolution, the action video at 720p will start to look bad, and at 1080p, it will look terrible.
Using "fixed visual quality" settings, as the words suggest, keeps the visual quality of the videos the same. Because it looks at the actual video during conversion and then determines what to use to achieve the set visual quality, the file-size fluctuates instead.
A romance video doesn't need as much an action movie, so a 2 hour SD romance video can end up around 600MB instead of the 2GB (2000MB) and still look identical (or better even). Of course going up in resolution will increase the filesize a bit.
For an action movie it works even better.
Using a "fixed bitrate" setting, to make the action scenes look great, you will need to convert the entire video using high quality settings, but, with most action movies, there is usually a 50/50 spread between action(fast) and story (slow). With the smart conversion settings, it automatically adjusts. Action scenes get more, slower scenes get less, and overall, better quality and smaller file-sizes.
So if you have a large collection of different types of video files, and would like to make them work with hardware-decoding for your tablet, give DVD Catalyst a shot.
Drag and drop your files, folders on top of the program,
select the HQXT version of your device profile,
In addition to batch-conversion and "smart" conversion settings, some other (unique) features of DVD Catalyst that might interest you are:
* Volume maximizer, which make the volume of all your video files the same loudness, regardless of what volume your source videos have,
* Batch-renaming, rename the video files to follow your own naming system, such as Anime Show 001 - Anime Show 255, TV Show s01e01 - TV Show s01e24,
* Automatic language and subtitle selection, for example, if the MKV file has English audio, select that, otherwise, enable Japanese audio and enable English subs.
* Ability to use your original folder to store the created video files, or recreate your folder structure on a different location.
