The free trial only support the re-encode mode. However I have not tested it as the trial download does not support the 'fast' encodeless mode. It says it is capable of splitting with re-encoding. There exists an inexpensive Windows tool to simple splitting. Not a simple one step process but not tedious. You can use VirtualDub to split a file without re-encoding. Any codec.įfmpeg -i %1 -map 0 -c copy -f segment -segment_time 600 -reset_timestamps 1 '%~dpn1_%%02d.mp4' It just splits into pieces, leaving the original file as is.įor those curious, the command is something like this. The good thing here is that I have the split not re-encode video. ffmpeg is free, but it is command line only so no simple UI to the do steps. Faster to just relink than type the prior paragraph.įor simple file splitting I provided an ffmpeg command file to do the splitting. I forget - did I link to you my 'Optimize Footage' tutorial? That contains some encoder settings for Handbrake developed and tested by which gives good edit performance in Hitfilm with high retention of detail and reasonable file size.Ībout 23:40 in this video. Handbrake can also change resolution of clips and can re-crop them, so Handbrake is your stop to conform timing (cuz you were also mixing 60p/30p footage if I remember correctly), fix VFR and crop your source footage.

It can also transcode VFR to CFR if you have variable frame rate footage to correct. Handbrake is an excellent, free choice for mp4 transcode. Splitting segments would be done with a third party transcoder. Splitting into shorter files means you'll be able to start editing the early segments while Hitfilm is caching later segments. There's a few boring techie reasons for this, mostly due to caching and backend stuff, but we'll stick with caching - if you load in like a 90 minute file Hitfilm has to cache the whole thing before you can edit. I usually recommend splitting long clips to 10-15 minute segments. In general Hitfilm (and, really, any NLE) will perform better with shorter clips (admittedly Hitfilm slows down more with super long clips than, say, Vegas Pro).
