Why is video playback so choppy?
I am a novice video editor. I have been using Blender's VSE for some small projects. I recently downloaded HitFilm Express as I had heard many good things about it. What I realized while using it is that the video playback is extremely choppy. A 1080p video with either 30 or 60 fps plays like a 10/20 fps video.
To check whether my system was responsible for this, I used some other video editors, including Davinci Resolve, Olive and Adobe Premier Pro. I had far better video playback on Davinci Resolve and the smoothest video playback ever on Olive and Premiere Pro for the same video files. Even after adding text and some animation, Premier Pro was working flawlessly without any sorts of frame drop.
Now I want to ask what could be the reason for programs like Premiere Pro or Olive to play the video with such smoothness. Even Davinci Resolve was playing it smoothly, until I added some transitions which resulted in some few frame drops but good performance overall.
What I have tried:
To get a smooth playback in HitFilm, I first lowered playback quality and resolution to 1/2 and then 1/4 but it still didn't play it smooth enough.
Without even adding any transitions, I could still easily see the drop in frames
Next I tried creating proxy/pre-renders. It helped a little. I could play my videos at a reasonable fps but when I added simple text animations over it, Videos still wouldn't play smoothly.
Why can't Hitfilm play these smoothly when Davinci and Premiere Pro provide good playback without even going into proxies ? Don't get me wrong. I have come to love Hitfilm. I prefer it over Davinci because its far easier to use and provides a similar interface to Premiere Pro. But I would seriously like its performance to be improved a bit.
My system is not super beefy but it is fairly specced as I ws able to work on Premiere Pro and Resolve smoothly. My specs are as follows:
8 GB RAM
256 GB SSD + 500GB HDD
GTX 950 - 2GB
Is it too under-powered to run Hitfilm ? or Does Hitfilm not properly support GPU? Whatever it is, some help would be appreciated.
I have a good playback experience with Premier Pro so HitFilm's performance shouldn't be much different either. I really want to use HitFilm. Adobe is too pricey and I don't plan to learn Resolve and its giant node editor. (I am lazy lol). Olive is good but really underhanded when it comes to features. I sometimes use masking so Olive is not going to cut it. I have been using Blender but it also doesn't have some video editing features I am looking for. Hitfilm is the only one that features everything I want for free but this choppy playback is really making me not want to use it.
