Moderator jfk Posted January 18, 2019 Moderator Report Share Posted January 18, 2019 This is an error in configuring your production computer. ]The display computer is NOT playing at all, video or otherwise. Multiple network ports are active and the UDP traffic is going out the wrong port (transport commands are UDP, file transfer etc are TCP, so the TCP activities get through regardless. Either turn off all network ports except the WATCHOUT port or re-order the network ports properly. This has been covered in the forum multiple times before, next time search first. 0 Quote Link to comment Share on other sites More sharing options...
christopherav Posted April 1, 2019 Report Share Posted April 1, 2019 Hi we are an upcoming watchout users, we need to know how we tell the creative guys to make videos? like format , codec if the videos within full hd 1080p resolution? Also if the video resolution goes above full hd? some creative guys ask so much information about videos when we ask them to make in .HAP codec, which is the best format above 4k? codec? frame rate? compression rate? bit rate? Also to make Alpha hap video what is the best codec? what is HAPQ? it would be helpfull if someone can answer my queries.. Thank you. Christi. 0 Quote Link to comment Share on other sites More sharing options...
Alex Ramos Posted April 1, 2019 Report Share Posted April 1, 2019 The way I see it, there is no "best". Will depend on hardware capabilities. I'm using ffmpeg to convert files. -> Hap -> 25, 30 or 60fps depends on the playback device -> Hap automatic -> Hap automatic -> Hap Alpha -> HapQ is a higher bitrate, larger files, better quality. Here are my ffmpeg settings: ffmpeg -i [input file] - dn -an -vf yadif -r 25 -vcodec hap -format hap [output file] ffmpeg -i [input file] - dn -an -vf yadif -r 25 -vcodec hap -format hap_alpha [output file] Check for more info: https://ffmpeg.org/documentation.html https://hap.video/ https://vdmx.vidvox.net/blog/hap 0 Quote Link to comment Share on other sites More sharing options...
christopherav Posted April 9, 2019 Report Share Posted April 9, 2019 I heard there is some convertor from Adobe , which can convert any content to .HAP ,.. can you advice which convertor is this? also need to know for hap video can we give some compression to reduce file size? if yes what would be the good compression percentage? 0 Quote Link to comment Share on other sites More sharing options...

christopherav Posted April 16, 2019 Report Share Posted April 16, 2019 if i have to convert a sample.mp4 video to hap video what would be the command? and if i have to put some compresssion to it, what would be the best compression rate? how would be the command goes? 0 Quote Link to comment Share on other sites More sharing options...
Guest DavidA Posted April 16, 2019 Report Share Posted April 16, 2019 Hi! You have to decide on the compression rates yourself as I have no idea on how your system is setup nor what you want to achieve. Here are an example to convert to HAP. set input="E:\video\test\smple.mp4" ffmpeg.exe -i %input% -an -ss 120 -t 30 -c:v hap -format hap -chunks 4 -y bbb_2160p30_hap.mov ffmpeg.exe -i %input% -an -ss 120 -t 30 -c:v hap -format hap_q -chunks 4 -y bbb_2160p30_hapq.mov Where: -i = input file -an = no audio -ss = start stream time (seconds), you can skip this option -t = duration (seconds), you can skip this option -c:v = codec for video -format = codec specific format (can be hap, hap_q or hap_alpha) -chunks = number of chunks for multi threaded decoding -y = over-write output file without prompting, you can skip this option 0 Quote Link to comment Share on other sites More sharing options...

christopherav Posted April 17, 2019 Report Share Posted April 17, 2019 Am trying for smooth playback and reduce file size by compressing the media file.. 0 Quote Link to comment Share on other sites More sharing options...
Alex Ramos Posted April 17, 2019 Report Share Posted April 17, 2019 Christopher don't take this the wrong way, but you need to do some research on your one. Use google and youtube. Me and David give you all the info you need in the thread to convert any video to Hap using FFMPEG. About the compression rate, HAP has no adjustable ratio, its fixed, use Hap for good image quality and use HapQ for better quality. 1 -> Download FFMPEG for Windows from ffmpeg win64 2 -> Extract the contents of the Bin folder to your c:/windows/system32/ ignore the other files (This is not the correct way to do, but it's the easiest) 3 -> Place the attached .rar file on you Desktop and extract 4 -> Drag and Drop the original video file to the .bat, the new converted file will be placed on the Desktop Desktop.rar Edit: Hap requires the video resolutions to be multiples of 4. The .bat files will check the resolution of the input file before converting, and if needed change it to the nearest multiple of 4 number. Ex: original video 320x282 after conversion 320x280 0 Quote Link to comment Share on other sites More sharing options...
Dataton Partner RBeddig Posted April 18, 2019 Dataton Partner Report Share Posted April 18, 2019 Smooth playback depends mostly on file size, hardware specs and computer tweaking. I assume that your server is completely tweaked following the tweaking guidelines for Win 7!? Are your SSDs using RAID-0 configuration - and is WATCHOUT installed on this SSD raid? Is your OS on a separate SSD or at least on a separate partition? Have you checked the reading speed of your WATCHOUT SSD? Since you're using an 8-core CPU it might be a good idea to use chunks when encoding HAP. 0 Quote Link to comment Share on other sites More sharing options...
christopherav Posted May 7, 2019 Report Share Posted May 7, 2019 Mr David thanks for all ur support. now i understood to convert videos to hap and hap.q format.. but hap.alpha isnt working.. the output video not coming as transparent video. anyways thank you so much again.. 0 Quote Link to comment Share on other sites More sharing options...

christopherav Posted May 8, 2019 Report Share Posted May 8, 2019 am using fmpeg convertor to convert. am using command for conversion ; ffmpeg.exe -i %input% -an -ss 120 -t 30 -c:v hap -format hap_alpha -chunks 4 -y bbb_2160p30_hap.mov is this right command to convert normal video to hap_alpha ? 0 Quote Link to comment Share on other sites More sharing options...
Alex Ramos Posted May 10, 2019 Report Share Posted May 10, 2019 I don't know what you mean by "normal video" This only works if the original video is already using alpha channel. Ex: Apple Animation+ --> HapAlpha, Apple ProRes 444 --> HapAlpha PNG sequence+ --> HapAlpha This is the simplest command I can think of. ffmpeg -i [input file] -vcodec hap -format hap_alpha [output file.mov] 0 Quote Link to comment Share on other sites More sharing options...

MP4 (H.264) uses temporal and spatial compression and depending on the settings in the encoder can be compressed quite a lot. The back draw of this is that the CPU needs to buffer a lot of frames - even more if you compress B-frames as well - to recalculate the individual frames in real time. I've seen a 4K video compressed to less than 1 Mbit/s which then played back with 1-2 fps on a quite powerful server as a result. HAP is far less compressed and does not use any temporal compression to my knowledge.This makes it far easier for the server to render those files while the CPU is almost asleep. I'm not aware of any settings in ffmpeg to increase compression. 0 Quote Link to comment Share on other sites More sharing options...

The MP4 (H.264) format does not hold any information on transparency. Transcoding this to another format will not generate the extra byte needed for the transparency. 0 Quote Link to comment Share on other sites More sharing options...
