I am trying to convert a Torrent video file to a mp4 Video File. The Torrent file was listed as "application/octet-stream" which I believe means the file type is hidden. I posted the Torrent file on my computer and I believe it was listed as an "avi" video type file. I tried using the latest version of Wondershare Video Converter to convert it, but was unsuccessful (It read "Failure to import file" and "Please check if the file format is supported"). Can anyone help me with this issue? (The video is in the Public Domain so I don't feel like I am ripping someone off)

Kazam

Kazam Screencaster is what I use.
Kazam will convert anything you can see on your screen, regardless of its format, to MPEG-4 video (video/mp4). Kazam makes a perfect digital copy of any video file you have.

I wouldn't recommend handbrake. I looked into it to convert my ripped blurays to mkv. The video quality setting isn't well documented and I have no idea what what's going on if you want to try to convert lossless. Converting a single movie would take forever and the file size is astronomical. Converting a typical 40GB movie file size was well over 100GB when I shut it down 12 hours later and progress wasn't much past 50%. The computer used was a i7-4790k OC'ed to 5GHz with 16GB of ram and using Samsung Evo SSDs, not the best but no slouch either. Tests using compression were MUCH faster and file size was reasonable so if the OP wants to compress the original file it could be an option.

What video compression codec do you use that is lossless? Have you turned GPU hardware acceleration on? Do you use CPUZ to watch your CPU speeds when encoding, it may be throttling?

What handbrake settings did you use? I've been using handbrake for years and conversions typically take under 30-40 minutes for a 2 hour movie. For example Oceans 8: 1:50 long movie - I got it down to 1.8GB using MPEG4 H264 10 bit (for max compatibility) 1920 x 1080 24 fps AAC audio 2 pass encoding. The 720p size would be ~900M using H264. Modest difference in quality to the original original BR video - a slight loss in colour saturation and detail in fast moving scenes if you look closely. But H264 is an older codec, there are more effective codecs available

Other codecs will result in different compressions and quality, for example HEVC/H265 will get you 2X the compression at the same video quality as H264, or significantly better quality at similar compression rates. But encode times for H265 is longer than H264, for me typically 2X longer.

The constant quality / average bit rate setting will make a significant difference in encode time as well as file size and picture quality. I usually set it at a bit higher rating as I prefer quality over size.
handbrake is used almost exclusively on YTS.am by contributors if you are familiar with the site/content.

Another good app is WinX DVD Ripper

Hey Promo,

This was a while ago I tried this so I downloaded the newest handbrake and am running some tests. This time the source is a BD rip on a NAS with native BD file structure. It's being saved on the local computer on a mechanical drive - SSD only had ~30GB free and I didn't want to risk it. First run using H264 1920x1080, frame rate is same as source which I'm assuming is 24fps and I used constant frame rate. The original was 33GB but that is the entire BD, menu structure, extras and all, so I would guess the feature was about 25GB I'm guessing. With the video quality slider set at the default 22 the conversion took about 50 minuted and file size is 2.5GB. Sounds reasonable.

I'm running a test now all the same settings but the video quality slider set to 0 "lossless". The estimate is saying it will take about 80 minutes, and they "warn" the file size will be the same as the source so we'll see. It's looking like I might have to eat some crow though! Maybe things have been fixed since I last tried it. FWIW I'm only interested in a bit perfect conversion. I just want to get it into mkv format to make playback easier than the native BD structure but I don't want to lose ANY quality and I don't care about file size as long as it's close to the original size. I'll report back with the results.

The problem with handbrake is the ancient, poorly described interface. You have to be a techie and tinkerer to use it. You definitely sound like a techie so you should be fine with time. Lots of guides available, that's how I learned it.

At 1920x1080 and default quality a 2.5GB file = a ~2.5 hour movie. Is that right?

Your PC is faster than mine, I'm guessing you have a good video card too? I have a 1080 video card and use GPU acceleration. Suggest you check that handbrake is configured to use the GPU acceleration (I think it does by default, but not sure).

I learned something, I didn't realize you could go to zero .... so that's where your lossless come from. Cool! It makes sense that the final file would be close to the original - basically you are just changing container formats.

No eating crow - this is how we all learn and benefit from sharing info. Because handbrake has worked for me and YIFY uses it, I've never bothered looking at alternatives. There's probably newer, better programs out there.

Have a look at HEVC/H265. I understand it's much better quality than H264. I can't use 265 as my Western Digital player doesn't support it, but I'm currently building a HTPC with Plex, so that problem will go away.

You mean, like nachos or Pringles? C'mon over, but you have to promise not to talk during the movie and no washroom breaks.
Kind of an inside joke with Brewwguy and I but since you said Pringles, I'd watch a movie with you.

Now if you said, ruffles - that would have been fighting words. Lol.

I'll give you something else to eat. ^^^^

PS - is this a video I can view???? LOL
Well with you I know that could mean a couple things. Did you have something specific in mind? Like a taco???

Also it is a video you can watch, but it's starring Clint Eastwood. Not sure if that would be disappointing for you! LOL

BTW Pringles? Really? I'm known to make some pretty good corn if that sounds better.

The movie I used was Gran Torino which IMDB says is ~2hrs long. Maybe the constant frame rate setting pushed up the file size a bit? I did little reading about using the GPU but what I found said it will make the conversion faster but CPU conversion slower but more accurate, since I'd only be interested in a bit perfect conversion I didn't look into it any further. And no my vid card is pretty dated, GTX285 IIRC, but it's water cooled and OC'ed so I'm getting what I can out of it.

Ok so I'll hold off on the eating crow (especially since Jess seems to have an alternative in mind!) but the lossless conversion I did resulted in a 17GB file. Seems a little optimistic to me since the entire BD was 33GB but kinda reasonable and a mile better than my last attempt. I didn't check in on it to see if the conversion time was accurate but it was less than overnight so again better than my lest trials. Certainly worth looking farther into. I have no idea what went on the last time I tried this, maybe the software has been fixed but could very possibly been a DFU issue. Thanks for making me revisit this and prove myself wrong. I love learning new shit too!

I'm still not above buying software to do the conversions. I have about 400 BDs (yep that's about 16TB worth) to convert so anything that makes it easier will probably pay for itself.
