Another good suggestion by Bigred.
We are all getting older and electronics smaller. It’s hard to see if your soldering blobs are okay!
Those blobs can reflect the light in a way that it’s not visible anymore to check them.
So i took Bigreds advice, and bought a G1200 Microscope.
It’s a cheap but helpfull little gadget.
- 1-1200 times zoom
- 7inch screen (720p)
- SDcard
- Lipo battery
- Recording on micro sdcard in 12 mega pixels pictures and 1080P Video.
(even got a timer) - Focus button, and extra lights (There is a light source in de camera head, which can be adjusted by a knob)
- When connecting to your pc, you get 3 options
- PC Camera ( … so you can record using your pc with for example OBS)
- Mass Storage, to read the SDCARD
- Rec_mode ?!? – No idea yet
Below some examples:
SDCard Access:
Access to the sdcard is a little hard. Connecting via Mass Storage is a solution. But i’ve put a little piece of tape to get the card in or out of the slot.
You can view the recordings on the Microscope itself. So i was wondering, can it play any other movie files?
I placed different MOV files on the sdcard, but the microscope skipped the ones i places on the sdcard myself.
I started to look at the metadata, and saw a Codec ID
“qt 2016.04.21 (qt )”
mediainfo VID_001.MOV General Complete name : VID_001.MOV Format : MPEG-4 Format profile : QuickTime Codec ID : qt 2016.04.21 (qt ) File size : 551 MiB Duration : 12s 0ms Overall bit rate : 385 Mbps Encoded date : UTC 1904-01-01 00:00:00 Tagged date : UTC 1904-01-01 00:00:00 Video ID : 1 Format : AVC Format/Info : Advanced Video Codec Format profile : Main@L4.1 Format settings, CABAC : Yes Format settings, ReFrames : 1 frame Codec ID : avc1 Codec ID/Info : Advanced Video Coding Duration : 12s 0ms Source duration : 12s 360ms Bit rate : 14.5 Mbps Width : 1 920 pixels Height : 1 080 pixels Display aspect ratio : 16:9 Frame rate mode : Constant Frame rate : 25.000 fps Color space : YUV Chroma subsampling : 4:2:0 Bit depth : 8 bits Scan type : Progressive Bits/(Pixel*Frame) : 0.280 Stream size : 20.8 MiB (4%) Source stream size : 21.3 MiB (4%) Language : 33 Encoded date : UTC 1904-01-01 00:00:00 Tagged date : UTC 1904-01-01 00:00:00 mdhd_Duration : 12000 Audio ID : 2 Format : PCM Format settings, Endianness : Little Format settings, Sign : Signed Codec ID : sowt Duration : 12s 0ms Source duration : 12s 288ms Bit rate mode : Constant Bit rate : 128 Kbps Channel(s) : 1 channel Channel positions : Front: C Sampling rate : 8 000 Hz Bit depth : 16 bits Stream size : 188 KiB (0%) Source stream size : 192 KiB (0%) Language : 33 Default : Yes Alternate group : 1 Encoded date : UTC 1904-01-01 00:00:00 Tagged date : UTC 1904-01-01 00:00:00
Tried to change this with ffmpeg, but it would not change the way i want.
ffmpeg -i VID_002.MOV -c copy -map 0 -brand 'qt 2016.04.21 (qt )' VID_007.MOV mediainfo VID_007.MOV General Complete name : VID_007.MOV Format : MPEG-4 Format profile : QuickTime Codec ID : qt 0000.02 (qt ) <--------------- nope
