Recently, I am trying to batch convert videos like MKV, AVI, and M2TS together to MP4, however, I am getting into troubles. I am running Windows 10 Pro 64-bit with 8GB RAM and Intel Core i7 inside and the converter always gets stuck when I do batch conversions.

I was adding around 50 videos in MKV, AVI, WMV to convert to MP4 (each video is 30 minutes in length) using the batch converting feature. Batch converting videos starts just fine but the memory usage goes up and up as time goes on. Eventually, after approximately 24 videos, the memory usage of the program hits 3.6GB (and rising) and then the program stops encoding. There are no error messages, no windows pop up, the program doesn’t crash or anything like that – the program remains on-screen but the progress bar stops rising any higher (and the file size of the video in progress stops getting any bigger).

I imagine that the problem could be that the program is only 32-bit so it stops working when memory usage hits 3.6GB. The best solution would be to recode the program and release a 64-bit native version so that it releases the memory when the current video has finished encoding.

This is how it should work:

  1. Create a batch job by adding videos to be encoded.
  2. Start encoder.
  3. After each video has finished encoding, release the memory for that video. You could even have the finished video removed from the batch job listing because once the encoding has finished, it’s done so no need to re-encode.
  4. Doing it this way, the memory footprint should remain low and the issue with the memory cap of 3.6GB will never arise.

However, there does not seem to be any updates on this when I come across this issues in the past two months. So the possible solution of a 32-bit program being stuck in batch converting is to limit the videos. As far as I can see, 20 videos are safe to batch convert.
