Hitfilm timeline 4k performance demo video
I am putting this is a new thread to not take other threads off topic.
@logic718gmailcom commented in other threads on Hitfilm 4k performance. I post this just to show what basic 4k performance you can get in Hitfilm with different media file types. There are very dramatic differences. The viewer is at FULL.
My machine: flat 4Ghz i7 4770k, 16GB ram, GTX 980, 7200 RPM 1TB disk.
EDIT: Cineform and Prores are now implemented natively in Hitfilm. Better performance.
I have four sample files shown.
- GH4 UHDp24 camera file. MOV renamed to MP4 for better performance. 81.7Mbps. If you want to know why I changed the file extension for performance read this thread. EDIT:As of Hitfilm version 6 the rename is no longer necessary for performance.
- A BMCC UHDp24 Prores 707Mbps MOV file. This is a harsh very high bitrate file.
- A Norman fast decode AVC setting file generated UHDp30 res from a 1080p30 source. 84.8Mbps. The file is long at 5 minutes to show the time it takes for thumbnails and waveforms to display in Hitfilm. This delay mostly shows up on long media files. The thumb/waveform delay can interfere with playback at times.
- A Cineform (medium) AVI UHDp30 file generated from a 1080p30 source. 305Mbps
Summary. All played back smoothly. Single media stream on NLE timeline test.
- The GH4 camera AVC is very slow to decode compared to the others. Scrubbing and trimming is laggy. Workable?
- The fast decode AVC is reasonably quick. Probably workable.
- The Cineform AVI file flies. No lag. Best performance.
- The BMCC Prores files is quite fast to trim/scrub. A bit heavy on decode/playback. Occasional, not repeatable, tiny hiccups. Not too surprising given the bitrate. A standard bitrate Prores file should perform better.
