![]() " Handbrake is not properly converting Canon XF705 H.265 files. Does that mean Handbrake cannot deal with H.265 MP4 files with muti-audio tracks? - Raymond Lee" H.265 file Audio Drops in Vegas Pro 14 timeline When I check the MP4 file in Mediainfo, it also only shows 2 single channels. When I check my audio tabs, it shows only one channel. I then take that into Handbrake to render to various devices and formats and ALL my GoPro Hero 7 files are in mono. ![]() " I am rendering out a project in Media Composer to 1080p 35mbps in an MP4 format. Handbrake does not see H.265 file as stereo Can we convert H.265 video to other format via Handbrake without any problem? Along the top row are six buttons where you can manipulate essential functions, such as opening your source file, adding a job to the queue, and a simple "Start" button, which says it all. The GTX 1660 does H264 at about 117fps for the same 4k footage.Handbrake is without a doubt, one of the easiest video converter programs around. ![]() It would report a speed of 23fps which is alot lower than I'd expect, so might be a driver issue, ffmpeg issue or settings issue. The progress would stop updating after a few secs but the encode would eventually complete. I was hoping to see what the H264 performance was like too, but the RX5700XT seemed to have troubles encoding H264 with FFMPEG. As you'd expect, x265 Very Slow (0.8fps) was by far the best picture quality and was only ~15% larger than x265 Medium. With both the RX or GTX, I found it hard to match the quality of x265 Slow (5.2fps) without the filesize becoming crazy big. But the filesizes were bigger and the picture quality a little more blocky than the GTX 1660. ![]() The GTX 1660 was able to get much closer to x265 medium's quality for the same size, but to close the gap, the file size needed to inflate by about 25%.įor what it's worth I did the same encodes on a slower PC with a (non-Turing) GTX 1650 (same drivers and ffmpeg settings) and got 120fps. If the footage is bright and low motion, most people wouldn't notice the quality difference for the same file size. This resulted in about double the size file for almost as good picture quality. In terms of the picture quality, I had to reduce the QP a lot to get the RX5700XT to compete with a x265 medium encode. I could squeeze 105fps out of the GTX1660 with lower quality settings (that I wouldn't use). I toyed with a number of encoding params, but for the RX5700XT it never got faster than 63fps. In terms of performance, it is slower than the GTX 1660. The system became very slow to respond while encoding 32 at once too. Although more than 40 would have probably maxed out the 8GB GPU memory. It looks like the RX5700XT doesn't restrict the number of concurrent encodes. I encoded to HEVC using CQP 24 on the GFX cards and CRF 20 for x265. The input file was a ~2GB h264 4k (4096x1716) Trailer. I used the latest stable FFMPEG on Windows 10 without Hardware Accelerated Decoding (turning it on halved the performance). In short the RX 5700XT appears to have no limit on how many concurrent encodes you can do, and runs at about 63fps for a single 4K HEVC encode. Never heard back from AMD, but I was able to borrow a R9-3950x system which had both a RX 5700XT and a GTX 1660 in it.
