Trimmer & Edit playback freezing - MPEG 2

Hi there,

I can shortly move the playhead then 20 seconds Hitfilm is calculating, then I can move Playhead a bit and so on

HAving put the media in Editor seems to be a bit better.

Proxying gets aborted with some errornous frame.

In Premiere Elements 12 this very footage works.

Is there something wrong with this clip?

Thanks in advance

  • Your clip is interlaced and HitFilm greatly prefers progressive sources. Try dropping the Deinterlace effect on it and see if it improves. If not you may have to deinterlace and transcode it first before using it in HitFilm

  • Which tool is suited to deinterlace and transcode?

    What would be the optimal target format for hitfilm?

    Ok, Hitfilm isn't particularly fast with video decoding. That said...

    You're footage is 1440x1080 interlaced. Hitfilm doesn't want to deal with interlaced footage, so it's having to deinterlace on the fly. 

    Best bet is to follow the tutorials here. Your issue isn't vfr, but I think this tutorial sets a Progressive flag. The second tutorial has optimized settings for Hitfilm.

  • To deinterlace in Handbrake you have to apply it under the Filters tab. I would enable deinterlacing and choose Bob as the method.

    Then in addition to the settings in the video @Triem23 linked to I would select Constant Frame Rate and double it from what it is now to 50 fps.

    Unfortunately there's no absolute 'best' way to deinterlace with what works best depending on the source footage. There are some good tips here if you want a little more info.
