A video shared on social media shows an overhead shot of a table at a polling place (it's not clear where). There are two people at the table. A man is reading ballots, a woman is filling in ballots. This is presented as evidence of voter fraud.
It is actually the standard practice of duplicating or "transposing" damaged ballots so they can be read by the counting machine, as explained in this Michigan Board of Elections training video from 2016.
The process uses two election inspectors of different party affiliations to avoid fraud. Here's the full process from the Michigan election officials manual.

DUPLICATING BALLOTS: Ballots must not be duplicated until after the close of the polls. Exception: If the duplication of absent voter ballots will be carried out at an absent voter counting board precinct, ballots may be duplicated and tabulated throughout Election Day; it is not necessary to wait until after the close of the polls to begin the duplication process.
The procedures for duplicating ballots are detailed below:
After identifying the ballots which must be duplicated, count out an equal number of unused ballots and remove the ballot stubs. At the top of the first “original” ballot to be duplicated write “1”; at the top of the blank ballot that will be used to create the “duplicate” write “Dup 1.” Follow the same numbering system for the remaining ballots which must be duplicated, e.g.: “2” – “Dup 2”; “3” – “Dup 3”; etc.
Duplicate the ballots using a reader-checker process with two election inspectors who have expressed different political party preferences. One election inspector calls the valid votes from the “original” ballot as the second election inspector records the votes to the “duplicate” ballot.
After completing the duplication process, the election inspectors who handled the procedure must verify that:
1) the “original” ballot is labeled at the top with a number “1” and the corresponding “duplicate” ballot is labeled at the top with “Dup 1” and
2) that all valid marks have been transferred from the “original” ballot to the corresponding “duplicate” ballot.
As explained above, this same numbering scheme is continued for all ballots requiring duplication. The second “original” ballot to be duplicated is numbered “2” and the “duplicate” ballot is labeled “Dup 2,” etc.
After the work is verified for accuracy, all “duplicate” ballots are tabulated. All “original” ballots are placed into a special envelope labeled “Original ballots for which duplicates were made and tabulated.” The special envelope is sealed into a ballot container along with all other used and unused ballots following the close of the polls.
